CVE-2026-58257
HighCVSS 7.2Summary
In GRR prior to version 4.5.0, the database restoration feature fails to enforce or validate file paths. A user with administrator privileges can manipulate input to read or delete arbitrary files on the server, causing sensitive file disclosure and denial of service through file deletion. The impact is amplified when the server runs with elevated privileges.
Risk Assessment
Arbitrary file read and deletion by an administrator can lead to data leakage and service unavailability, especially when the server runs with elevated privileges.
Recommendation
Update GRR to version 4.5.0 or later, which fixes this vulnerability.

In GRR prior to version 4.5.0, `maj.php` reflects the `forcemaj` parameter without adequate escaping when installation files remain accessible. Removal of these files is not automatic. An attacker can craft a URL that executes arbitrary JavaScript in a victim's browser when the victim accesses it.
- CVE-2026-58256Critical
In GRR prior to version 4.5.0, an administrator can inject malicious PHP through LDAP connector configuration parameters such as `ldap_filter`, poisoning `/personnalisation/config_ldap.inc.php` and enabling remote code execution. The administrator must first successfully connect to an LDAP server, which can be attacker-controlled, and then submit malicious input on the subsequent connector settings page.
